Hiya Differcult. Do not feel dirty and cheap, it's the lad who should feel that. He must do it to alot of other girls... He was using you and bragging to his mates about what he'd done. Ditch this guy straight away! They aren't worth it. Just get to know a lad first, as friends and see how things evolve.

What he did isn't right. How can someone say "I love you" and not mean it? Dont let this lad get you down, at least you didn't go all the way, thats obviously what he wanted. Good for you to stop before it got all the way.
Good luck x
